Harmful Algal Bloom (HAB) Update

Harmful Algal Blooms (HABs), made of blue-green algae (cyanobacteria), can occur in lakes and reservoirs and may contain toxins that are a health hazard to humans and animals.

The most common symptoms of exposure to HABs include gastrointestinal illness and skin irritation. Some toxins can cause liver, respiratory, or neurological problems.

HABs may look like pea soup, green or blue paint, or a scum layer floating on the surface.

Be alert! Avoid water that:

  • looks like spilled paint or antifreeze
  • has surface scums, mats, or films
  • is discolored or has streaks
  • has green globs floating below the surface

Avoid swallowing lake water!

If you’ve been exposed to a HAB, contact the Utah Poison Control Center at 800-222-1222.

HABs can be reported to the Utah Department of Environmental Quality at 801-536-4123.
